| Abstract | This research aims to study concrete paving blocks made from bagasse ash and calcium carbide residue, using sand and calcite residue as fine aggregates. Bagasse ash is a by-product from biomass power plants, calcium carbide residue is a waste material from acetylene gas production, and calcite residue sources from limestone mining. The concrete paving blocks were produced with a binder-to-aggregate ratio of 1:3 by weight and a water-to-binder ratio rang from 0.45 to 0.63. The bagasse ash-to-calcium carbide residue ratios were 90:10, 70:30, and 50:50 by weight of the binder, with hydraulic cement contents of 10%, 20%, and 80% by weight of the binder for the 70:30 (the ratio of bagasse ash to calcium carbide residue mix). The effect of replacing sand with calcite residue as a fine aggregate was studied, using ratio of bagasse ash to calcium carbide residue with a 70:30 by weight and varying the sand-to-calcite residue ratio with 100:0, 75:25, 50:50, 25:75, and 0:100 by weight. The compressive strength was investigated at 3, 7, 14, and 28 days and the water absorption was determined at 28 days. The results indicated that a bagasse ash-to-calcium carbide residue ratio of 70:30 by weight, with 80% cement in the binder, produced the highest compressive strength and lowest water absorption. Calcite residue was used as the fine aggregate, with a sand-to-calcite ratio of 0:100 by weight achieved the highest compressive strength, but lower than using 100% of sand. Nevertheless, the compressive strength of the concrete paving blocks made from bagasse ash and calcium carbide residue was under the standard of TIS 827-2565, with the greater than 17 MPa of compressive strength. This product is recommended for low-load-bearing applications. Furthermore, this study provides the potential of utilizing industrial waste, the reducing of cement use, the low production costs, and the contributing to environmental waste management. |
